Filed: 1983-11-18
Abstract: PURPOSE:To decrease the size of a laser light shield plate and reduce the size and cost of an optical pickup by arranging the laser light shield plate between a laser diode and a collimation lens. CONSTITUTION:A laser light shield plate 23 is supported with parallel leaf springs 26 which are each fixed to a fixed block 25 at one terminal, and fitted so that the shield plate cuts off laser light between a laser diode 15 and collimation lens at its neutral position and allows the laser light to pass through a hole part 231 of the shield plate 23 by the deformation of parallel leaf springs 26 when a force is applied as shown by an arrow D. Therefore, the light is projected from a convergent lens only when the shield plate 23 is pressed, and not projected normally. The shield plate 23 is arranged near the laser diode 15, so its side is reduced and the stroke of the movement of the shield plate may be small; the laser light shield device is reduced in size, contributing to the size reduction of the optical pickup.

Title: Telephone cable bridging sensor
Inventor: UIRIAMU SHII MATSUKURUAA
IPC: H04M3/22
Filed: 1990-08-16
Abstract: PURPOSE: To easily decide when the receiver of a telephone set is picked up and put back while the telephone line of the telephone set is busy by instantaneously indicating the changing state of the telephone line and utilizing the output signal of a detecting circuit. CONSTITUTION: When a relay 12 is engaged by means of a controller which picks up a receiver, the chip ring coupling section of the telephone line is directly connected to the input side of a diode bridge rectifier. When a second telephone set on the same telephone line is energized and the receiver of the second telephone set is picked up, the second telephone set adds the measurable impedance of the telephone line and an increased loop current is detected as a voltage change in a bridge detecting circuit 10. When a voltage drop occurs in the circuit 10, the frequency of a voltage-controlled oscillator 62 becomes lower in the output of the circuit 10. The output of a bridge sensor circuit is used for discriminating the change of the number of telephone sets which are actually simultaneously bridged to the same telephone line.
